A lever is a long rod or board that pivots on a fixed point called a fulcrum.The load is the object you need to lift. The effort is the force you use on the lever. Levers are commonly used as see-saws.
How We Use Simple Machines and Engineering In Real Life
We cannot imagine life without simple machines and engineering. We use simple machines every day.Sometimes your using a simple machine without even knowing it such as when you open or close the blinds, you are using a pulley. You are using a class 1 lever when you play on the see-saw and when you use a door you use a class 2 lever. We use engineering in many ways too. We use the engineering design process make building easier. The engineering design process consists of identifying needs, generating the design, testing and improving. So as you can see, we could not live without simple machines or engineering.
